Why Students Make Grammar Mistakes
Before we dive into specific errors, it’s important to understand why these mistakes happen:
- Thinking in your native language and translating directly into English
- Learning rules without practice
- Memorizing patterns instead of understanding meaning
- Not reviewing incorrect answers or feedback
Knowing the reason behind the mistake is the first step toward fixing it.
1. Subject-Verb Agreement Errors
❌ Common Mistake:
People write:
“She go to school every day.”
✅ Correct:
“She goes to school every day.”
📌 Why it Happens:
Students often forget to change the verb form depending on the subject.
🧠 Tip to Fix:
Always match the verb with the subject:
- Singular subjects use verbs ending in –s (he goes, she reads)
- Plural subjects do not (they go, we read)
Practice Tip:
Write 10 sentences using different subjects (I, he, they, we) and check the verb form.
2. Misuse of Tenses
❌ Common Mistake:
“I have finished my homework yesterday.”
✅ Correct:
“I finished my homework yesterday.”
📌 Why it Happens:
Students often mix present perfect tense with definite past time references like yesterday, last year, in 2010.
🧠 Tip to Fix:
Use past simple with specific time expressions:
- I met her last week.
Use present perfect with unspecific time: - I have met her before.
Practice Tip:
Make a list of time words and decide which tense they need.
3. Errors With Articles (a, an, the)
❌ Common Mistake:
“I have car.”
✅ Correct:
“I have a car.”
📌 Why it Happens:
Articles are tricky because some languages don’t use them.
🧠 Tip to Fix:
- a / an — use before singular, countable nouns
• a book • an apple - the — use for specific things
• the car I bought
Practice Tip:
Read aloud and try adding/removing articles — does the sentence still make sense?
4. Preposition Problems
❌ Common Mistake:
“I am good in English.”
✅ Correct:
“I am good at English.”
📌 Why it Happens:
Prepositions don’t always translate directly between languages.
🧠 Tip to Fix:
Learn common collocations (words that go together):
- good at
- listen to
- interested in
- arrive in / at
Practice Tip:
Create flashcards with preposition + verb phrases and test yourself.
5. Confusion Between Your and You’re
❌ Common Mistake:
“Your welcome.”
✅ Correct:
“You’re welcome.”
📌 Why it Happens:
These words sound the same but mean different things.
🧠 Tip to Fix:
- your = possessive (your book)
- you’re = you are (you’re amazing)
Practice Tip:
Replace you’re with you are in your sentence—if it makes sense, it’s “you’re”! If not, use “your”.
6. Wrong Word Order in Questions
❌ Common Mistake:
“You are coming?”
✅ Correct:
“Are you coming?”
📌 Why it Happens:
Students sometimes apply word order from their native language.
🧠 Tip to Fix:
In questions, the auxiliary verb (do/are/is) comes before the subject:
- Are you ready?
- Do you like music?
Practice Tip:
Turn statements into questions to practice:
- She is happy. → Is she happy?
7. Missing or Incorrect Use of Plurals
❌ Common Mistake:
“I have two book.”
✅ Correct:
“I have two books.”
📌 Why it Happens:
English makes plurals by adding –s, which is easy to forget.
🧠 Tip to Fix:
Add –s for most plurals:
- apple → apples
Exception: irregular plurals - child → children
Practice Tip:
Write the plural form of common classroom nouns.
8. Countable vs. Uncountable Nouns
❌ Common Mistake:
“I have much books.”
✅ Correct:
“I have many books.”
📌 Why it Happens:
Words like water, information, and advice are uncountable.
🧠 Tip to Fix:
Use:
- many → with countable nouns
- much → with uncountable nouns
Examples:
- many bananas
- much milk
Practice Tip:
Make two lists: countable and uncountable nouns; practice using them with many/much.
9. Incorrect Use of Pronouns
❌ Common Mistake:
“Me and him went to the store.”
✅ Correct:
“He and I went to the store.”
📌 Why it Happens:
Students often use the wrong pronoun case.
🧠 Tip to Fix:
Use subject pronouns (I, he, she, we) in the subject:
- Correct: She and I are friends.
Use object pronouns (me, him, her) only after prepositions: - Give it to me.
Practice Tip:
Replace the combined subject with a single pronoun:
- Me went… → immediately sounds wrong.
10. Run-on Sentences and Comma Splices
❌ Common Mistake:
“I went to school I forgot my homework.”
✅ Correct:
“I went to school, but I forgot my homework.”
📌 Why it Happens:
Students join two independent ideas without linking words or proper punctuation.
🧠 Tip to Fix:
Use:
- a comma + a conjunction (and, but, so, or)
- a semicolon
- or make two sentences
Practice Tip:
Spot long sentences in your writing — split them if they have two complete thoughts.
